3.7 System monitoring
Upper/lower current limitYou can enter an upper and/or lower current limit.
Example:
● "Viscosity of mixed mass is too high"; that is, the upper current limit has been overshot.
● "No load because drive belt is broken"; that is, the lower current limit has been undershot.
Note
The current limits are not activated until the class time expires, e.g. after 10 seconds for
class 10 (startup override).
If the current limits are overshot or undershot, the motor starter responds either by tripping or
with a warning.
Note
The current limits can also be deactivated.
Blocking time
The blocking time is the time during which a motor can be blocked without tripping. If the
blocking time expires and the block is still in place, the motor starter trips.
Blocking current monitoring
The blocking current specifies how much current is consumed by the motor (at rated voltage)
when the axis is blocked.
If the motor current exceeds the parameterized value for the blocking current, the motor
starter detects the block. Blocking time monitoring is activated from the point at which the
blocking current is exceeded. If the blocking current flows for longer than the parameterized
blocking time, the motor starter automatically generates a trip command.
